“…For example, 106 kg P ha −1 were applied before planting in 156 super-high-yield demonstrations for maize production in China (grain yield averaged 16.7 Mg ha −1 , Chen et al, 2012). These high P fertilizer recommendation often mislead producers into believing that simply increasing inputs will produce more grain.…”

“…In China, considerable research has been devoted to testing the high-yielding potential of crops without nutrient constraints. For example, maize yields of > 15 Mg$ha -1 have been reported in more than 195 fields over the past two decades [21] . Such yields are nearly three-times the average yield of 5.9 Mg$ha -1 in 2014 [2] .…”

Balancing crop productivity with resource use efficiency and beneficial environmental consequences is essential for sustainable agricultural development worldwide. Various strategies and approaches have been proposed and debated, but turning the concept into management practices in the field with measurable outcomes over several scales remains a challenge. An innovative approach, Integrated Soil-Crop System Management (ISSM), for producing more grain with greater nutrient use efficiencies and less environmental pollution is presented. The ISSM approach has been used in China, in field experiments as well as in thousands of farmer fields, to substantially increase the yields of maize, rice and wheat while simultaneously increasing nitrogen use efficiency and reducing environmental footprints. The scientific principle, implementation strategy and procedures of ISSM are discussed and examples of its demonstrated successes at local and regional levels across China are given. Perspectives for further development of ISSM and expanding its potential impact are also proposed and discussed.

“…Judicious K management is required to ensure high yield and quality for food security and to sustain soil productivity under intensive cropping systems (Pettigrew, 2008; Römheld and Kirkby, 2010). During high‐yield demonstrations for maize production in China, large amounts of K fertilizer are often applied; for example, 141 kg K ha −1 in 156 high‐yield demonstrations, with a high soil extractable K level (NH 4 OAc‐K, 239.9 mg kg −1 ) before planting (Chen et al, 2012). These high K fertilizer inputs have limited our quantitative understanding of K uptake requirements in high‐yield systems and often lead to the misconception that “more K results in higher grain yield”.…”

Understanding maize (Zea mays L.) grain yield in relation to K uptake requirements is essential for devising optimized K fertilizer management practices and agricultural policies to increase grain yield for food security. A database comprising 953 measurements was created using 56 on-farm and research station experiments during 2000 to 2012 in the North China Plain (NCP) to determine K uptake requirements and patterns of K accumulation pre-and post-silking with different yield levels. The K requirement Mg -1 grain yield (K req. ) in the K = Opt. treatment was 15.0 kg, which was lower than 20.0 kg in the K > Opt. treatment. In the Optimal K treatment, average K req. values were 15.0, 14.8, 14.8, and 15.7 kg for grain yields ranging from <8.0, 8 to 10, 10 to 12, and >12.0 Mg ha -1 , respectively. The relative consistency of K req. values with increasing grain yield was mainly attributed to an offset in the increase in stover K (from 14.0 to 18.1 g kg -1 ), an increase in harvest index (HI) from 0.49 to 0.54, and the stability of grain K concentrations (about 3.2 g kg -1 ). Higher percentages for K accumulation at the post-silking stage were observed with >12 Mg ha -1 (24%) and 10 to 12 Mg ha -1 (22%) compared to <10 Mg ha -1 (9%). In conclusion, maintaining adequate K supply and post-silking K accumulation is essential for achieving high-yield maize production.
